standardWindowButton returns nil

[UXDart]

Hi! I'm trying to create a window by code:
self = [super initWithContentRect:rect styleMask:NSTitledWindowMask | NSClosableWindowMask | NSMiniaturizableWindowMask | NSResizableWindowMask backing:NSBackingStoreBuffered defer:NO];

and I got an error saying that it was trying to add nil to an array. I found that the problem is in the line:
_standardButtons = @[[self standardWindowButton:NSWindowCloseButton],
[self standardWindowButton:NSWindowMiniaturizeButton],
[self standardWindowButton:NSWindowZoomButton]];

standardWindowButton: is returning nil for all 3 calls. any idea? I'm on 10.10.1

TIA

I found that calling for example [NSWindow standardWindowButton:NSWindowCloseButton forStyleMask:self.styleMask] fixes it.

I ran into the same issue when creating window programmatically.

Explanation (from docs):

class func standardWindowButton(NSWindowButton, for: NSWindowStyleMask)

Returns a new instance of a given standard window button, sized appropriately for a given window style.

func standardWindowButton(NSWindowButton)

Returns the window button of a given window button kind in the window’s view hierarchy.

@weAreYeah Is this repo still maintained? If I submit a PR for this, is anybody going to merge it in?

Btw. I was only seeing this error when I created window without specifying style masks for all three buttons, i.e.:

self.init(contentRect: rect, styleMask: [.titled], backing: .buffered, defer: false)

Once I added the appropriate style masks, everything works fine:

self.init(contentRect: rect, styleMask: [.titled, .closable, .miniaturizable, .resizable], backing: .buffered, defer: false)
